Michael Schumacher’s condition has not changed as the seven-time Formula 1 world champion is still being awoken from his coma, according to manager Sabine Kehm.

Schumacher suffered severe head injuries in a skiing accident at the end of December, and has been in a medically-induced coma ever since. It was revealed last month that efforts were being made to awaken the 45-year-old by gradually reducing his sedation, but a lack of updates had prompted many to fear the worst.

However, Kehm made clear that the wake-up process is a lengthy one, and that only information coming directly from those monitoring his condition should be considered valid.

“Michael is still in the wake up phase,” a statement from Kehm read. “The situation has not changed.

“Any medical information published which is not confirmed by the team of doctors treating Michael or has management has to be considered as not valid.”

Kehm’s comments follow a number of reports and quotes from neurologists that, despite having expertise in the field, are not directly caring for Schumacher. With head injuries being incredibly difficult to fully analyse and understand, any information or diagnosis given by those that are not associated with his care must be treated as pure speculation.

I had no idea when I found out several years ago that he was the richest athlete in the world.I would have thought Tiger or Jordan earned more, due to endorsements, but this Michael is the king.

Even in this day and age, head injuries are just baffling.

way back in the day they were saying he was making like 70 mil. a year.

I just find it unfortunate & odd, his whole career of being at risk of death, seeing several of his colleagues die. Never get hurt during his whole career, then after retirement on vacation this happens.
